The National Map is a collaborative effort of the United States Geological Survey (USGS) and other federal, state, and local agencies to improve and deliver topographic information for the United States. [1]
The United States remains virtually the only developed country in the world without a standardized civilian topographic map series in the standard 1:25,000 or 1:50,000 metric scales, making coordination difficult in border regions (the U.S. military does issue 1:50,000 scale topo maps of the continental United States, though only for use by ...

The logo of the United States Geological Survey (USGS) The Geographic Names Information System (GNIS) is a database of name and location information about more than two million physical and cultural features throughout the United States and its territories; the associated states of the Marshall Islands, Federated States of Micronesia, and Palau; and Antarctica.
The system dates to Nevin Fenneman's report Physiographic Divisions of the United States, published in 1916. [2] [3] The map was updated and republished by the Association of American Geographers in 1928. [4] The map was adopted by the United States Geological Survey by publication in 1946. [5]
The images, archived in the United States and at Landsat receiving stations around the world, are a unique resource for global change research and applications in agriculture, cartography, geology, forestry, regional planning, surveillance and education, and can be viewed through the U.S. Geological Survey (USGS) "EarthExplorer" website.
The Geographic Names Information System, developed by the BGN in cooperation with the US Geological Survey, includes topographic map names and bibliographic references. The names of books and historic maps which confirm the feature or place name are cited. Variant names, alternatives to official federal names for a feature, are also recorded.
